Tortise240

I just ran a compression test and with a cold motor it pulled 125-130 psi in every cylinder. #3 spark plug came out black and was gapped to .6 maybe it wasnt getting enough spark due to improper gap? I double checked the gap for the rest and they were all smaller than .8 but only #3 looked fouled

@Dose Pipe Sutututu i dont have the time or money for a nistune at the moment but as soon as i can send them my ecu ill get that board installed and tuned. Thanks for the reccomendation i didnt know about nistune before but it looks like the best tuning option by far...cant beat what is essentially a standalone for 500$! Knock sensors looked fine physically but i dont know how to check without nistune

@inmaniac Quite the conundrum indeed ill get a video up soon as i can, it would help alot to get a second opinion on how it revs under load, seem sluggish to me but maybe thats just because its so slow @Dose Pipe Sutututu Ima go check those knock sensors i hope its not that though cuz rb parts are hard to come by in the shitty ol UsA lol @vxsr33 Dyno time is too expensive where im located, and its a DET hence the issue with it feeling slower than a ka24

@drunken0elf @iruvyouskyrine @niZmO_Man Timing is at 15* all spark plugs look perfect sandy color and coils look good. AFM reads 11-12 on boost and 14-15.7 at idle or low throttle. My boost gauge says it holds 10psi which sounds about right for the stock turbo. Could there be a boost leak or busted turbo even though the gauge reads 10psi? It really does preform like an NA engine but it holds 10psi on boost and about -18 vaccum at idle. It seems to rev slow under load as well, maybe driveshaft issue? There is a clunk from the rear sometimes when i shift or hit the throttle hard which i believe is my center support bearing but i wasnt under the impression that it would cause a massive power loss like this

@drunken0elf @iruvyouskyrine I would hope its more powerfull than my 120hp 4banger accord which currently out runs it?

@niZmO_Man it has the stock ecu and stock everything, ive been in a stock rb20det powered s14 and it felt much faster, mine pulls as hards as a single cam KA @inmaniacmy honda accord is an old 4 banger i was just trying to emphasize how slow my s13 is lol something feels wrong fersure

Rb20det s13 runs perfect but slower than a civic Hey everybody, i just made this account because ive been browsing this site everytime i need to learn something about my engine(rb20det) and the info yall got here is incomparable to any forums in the US where its just a huge internet argument. With that being said i havent found anything on this forum that adresses the issues im having so here goes. I have a rb20det swap in my s13 running everything stock, its holding boost at 10psi, the wideband reads 11-12 on boost and around 15 at idle, the timing is set at 15* and everything appears to be running perfect except a little idle fluctuation from 680-780rpm and sometimes i need to hit the gas when cranking to start it. The major issue im having is my car is slower than my honda accord but seems to be running fine, i can feel the turbo spool and the boost comes on but its still very very slow. Any help would be greatly appreciated
